US President Donald Trump has dramatically escalated tensions with Iran by issuing a 48-hour ultimatum demanding the immediate reopening of the Strait of Hormuz, threatening to destroy the country's power infrastructure if Tehran fails to comply.

The threat comes after Iran moved to block the strategically vital waterway through which roughly 20 percent of the world's oil supply passes daily. Trump's ultimatum specifically targets Iran's power generation facilities, signaling a willingness to strike civilian infrastructure.

Tehran responded defiantly, warning that any attack on Iranian territory would trigger a devastating counterattack aimed at US energy infrastructure and allied assets across the region. Iranian military officials emphasized that they possess the capability to inflict significant damage on American interests throughout the Middle East and beyond.

The confrontation over the Strait of Hormuz represents one of the most dangerous flashpoints in the conflict, with the potential to disrupt global energy supplies and draw additional nations into the crisis. International observers have called for restraint on both sides, warning that an escalation over the strait could have catastrophic economic consequences worldwide.
